Analysis of complicated canal morphology of mandibular first premolar
摘要
Abstract
Objective:To investigate the complicated canal morphology of mandibular first premolar using conebeamCT(CBCT). Method:20 CBCT images of complicated canal mandibular first premolar were selected .The images wereanalyzed with 3D reconstruction software for the number and morphology of root, groove and canal. Result:17 single orfused root(85.0 %) and 3 double-root(15.0 %) teeth were record. The incidence of groove in complicated canal was 95.0%, and usually locate in mesio-lingual and lingual side. The canal configuration of mandibular first premolar was typeⅢ:25.0 %,typeⅤ:5.0 %,typeⅧ:15.0 %,typeⅨ:5.0 % and C-shaped canal:45.0 %,circumferential canal:5.0 %. The highestincidence of canal configuration is C-shaped cannal. Conclusion:The canal system anatomy of mandibular first premolaris complex.关键词
